Kevin Duane Ingram, 43, entered the plea before Muskegon County 14th Circuit Judge Timothy G. Hicks. Hicks committed to cap Ingram’s minimum sentence at four years in state prison. The judge is free to impose any maximum sentence because armed robbery is a life felony.

Sentencing was scheduled for Dec. 20.

The Panopouls Salon at 907 W. Norton was robbed at about 6:45 p.m. Oct. 20. The robber arrived on a bicycle, came into the salon carrying a steak knife and demanded money, Norton Shores police said.

The man took an undisclosed amount of money from the cash register and fled east on Norton Avenue.

Then, about 4:30 the next morning, a man called 911 from Summit Avenue and Fifth Street in Muskegon Heights saying he wanted to turn himself in, police said.

The man — identified as Ingram after he was arrested — admitted smoking crack all day and robbing the salon, police said.

Ingram’s address in court records is listed as 400 W. Laketon, which is the Muskegon Rescue Mission.
